Description
3
AVCC
PWR
+3.3V supply to the internal clock multiplier. This pin requires a 100nF decoupling
capacitor
6
AGND
PWR
Device analogue ground supply for internal clock multiplier
17, 30,
40
VCCIO
PWR
+3.3V supply to the ADBUS, ACBUS, BDBUS and BCBUS Interface pins (11..16,
18..23, 31..38, 41..48). Leaving the VCCIO unconnected will lead to unpredictable
operation on these interface pins.

Description
4
XTIN
Input
Input to 12MHz Oscillator Cell. Connect 12MHz crystal across pins 4 and 5, with
suitable loading capacitors to GND. This pin can also be driven by an external 12MHz
clock signal. Note that the switching threshold of this pin is VCC/2, so if driving from
an external source, the source must be driving at +3.3V CMOS level or AC coupled to
centre around VCC/2
5
XTOUT
Outpu
t
Output from 12MHz Oscillator Cell. Connect 12MHz crystal across pins 4 and 5, with
suitable loading capacitors to GND. XTOUT stops oscillating during USB suspend, so
take care using this signal to clock external logic
7
PLLFLTR
Input
External PLL filter circuit input. RC filter circuit must be fitted on this pin
8
TEST
Input
Puts the device into IC test mode. Must be tied to GND for normal operation
9
RESET#
Input
Can be used by an external device to reset VNC1L. This pin can be used in
combination with PROG# and the UART interface to program firmware into VNC1L. If
not required pull-up to VCC via a 47k resistor.*
10
PROG#
Input
This pin is used in combination with the RESET# pin and the UART interface to
program firmware into VNC1L.*
Table 3.3 Miscellaneous Signal Group
* These pins are pulled to VCC via internal 200k resistors.
